Question

4(x-2)=4+2(x-1) como resolve?
4(x-2)=4+2(x-1)
2(2x+5)-(4x-9)=3(3-4x)

Como resolve

Answer 1

Ola,

4 (x-2) = 4 + 2 (x-1)

4x - 8 = 4 + 2x - 2

4x - 2x = 4 - 2 + 8

2x = 10

x = 10 / 2

x = 5

2 (2x+5) - (4x-9) = 3 (3-4x)

4x + 10 - 4x - 9 = 9 - 12x

4x - 4x + 12x = 9 + 9 - 10

12x = 8

x = 12/8

x = 6/4

x = 3/2
